如何将文本文件加载到Tmemo（Android，C ++ Builder）

Question

I use C++Builder to make an Android app.

I try to load a text file into a TMemo , but there is an error:

No mapping for the Unicode charactor exists in the target multibyte code page.

I use TDirectory::GetFiles() to get a list of files and add them to a TListBox :

TStringDynArray list;
TSearchOption searchOption;

searchOption = TSearchOption::soAllDirectories;

list = TDirectory::GetFiles(SYS_TxtDirectory, "*.txt", searchOption);

ListBox1->Items->Clear();
for(int i=0;i<list.Length;i++)
{
    ListBox1->Items->Add(list[i]);
}

When I click on the ListBox, I get a filename with full path into this variable:

AnsiString txtFileName; //store txt filename with full path

I wish to load this file into a TMemo. But these codes cause the error:

Code 1:

Memo1->Lines->LoadFromFile(txtFileName); //<----run to here,error occurred

Code 2:

TStringStream * LrcFileStream;

LrcFileStream=new TStringStream();

LrcFileStream->LoadFromFile(txtFileName);

Memo1->Lines->LoadFromStream(LrcFileStream); //<----run to here,error occurred

delete LrcFileStream;

Code 3:

TStringDynArray list;

list = TFile::ReadAllLines(LrcFile); //<----run to here,error occurred

Memo1->Lines->Clear();

for(int i=0;i<list.Length;i++)
{
    Memo1->Lines->Add(list[i]);
}

Code 4:

TStringList *ss=new TStringList();

ss->LoadFromFile(LrcFile); //<----run to here,error occurred

for(int i=0;i<ss->Count;i++)
{
    TmpStr=TmpStr+ss->Strings[i];
}

delete ss;

How can I load a text file into a TMemo ?

Answer 1

These codes are working on Abdroid now.

TStringDynArray list; 
UnicodeString TmpStr;
list = TFile::ReadAllLines(LrcFile,TEncoding::ANSI); 
TmpStr=""; 
Memo1->Lines->Clear(); 
for(int i=0;i<list.Length;i++) 
{ 
    TmpStr=TmpStr+list[i]; 
}
